We are now using the ZIPBOLT™ UT Rail Bolt (13.600) on all Cooper Stairworks Preassembled Stairs. The ZIPBOLT™ UT Rail bolt is part of a program of fasteners and connectors ideally suited for the stair industry. Instead of fumbling with a nut, washer, and special wrench, the ZIPBOLT™ uses a standard hex style driver to fasten rail parts securely together. Easier, faster, and stronger, the ZIPBOLT™ UT Rail bolt is fast becoming the preferred choice of professionals.
This Pack includes 15 Bolts and 2 - 5mm Hex Drivers and written instructions with a hole marking template.
